The post you're responding to wasn't arguing for capabilities, it was arguing for ease-of-use and it was right.

Your comment is pointless and a straw-man argument.

The commenter wrote that Tailscale is easier to use than AWS anything, but it can't even stand near in terms of scope. It's like saying that my calculator is easier to use than Apple anything; useless astroturfing that adds nothing to the discussion.

They do support DNS, to answer your original question. But to this point, it's not useless because someone suggested they use an AWS service to accomplish what the article says was done with tailscale. So, saying tailscale is infinitely easier to set up is a very useful comment. Also true.

No, it's not even true. I really went to Tailscale to see an alternative to AWS suite. Turned out to be a sort of managed Wireguard instead.

Yes, you're right that "it can't even stand near in terms of scope", but the original comment did not argue that, the original comment gave an opinion about the usability (actually "to setup/manage", so more like the administrative efforts) of Tailscale, which is not the same thing as the scope of its abilities. Calling the comment misleading because the service has a smaller scope is then at best misunderstanding the original comment, at worst purposefully trying to derail the discussion.
